+Lock master DICT against schema operations
+
+Implementation
+--------------
+
+[ see comments in Dbdict.hpp ]
+
+Use case: Node startup INR / NR
+-------------------------------
+
+Master DICT (like any block) keeps list of alive nodes (c_aliveNodes).
+These are participants in schema ops.
+
+(1) c_aliveNodes is initialized when DICT starts
+    in sp3 in READ_NODESCONF from CNTR
+
+(2) when slave node fails (in any sp of the slave node)
+    it is removed from c_aliveNodes in NODE_FAILREP
+
+(3) when slave starts, it is added to c_aliveNodes
+    in sp4 of the starting node in INCL_NODEREQ
+
+Slave DIH locks master DICT in sp2 and releases the lock when started.
+Based on the constraints:
+
+- the lock is taken when master DICT is known
+  DIH reads this in sp2 in READ_NODESCONF
+
+- the lock is taken before (3)
+
+- the lock is taken before copying starts and held until it is done
+  in sp4 DIH meta, DICT meta, tuple data
+
+- on INR in sp2 in START_PERMREQ the LCP info of the slave is erased
+  in all DIH in invalidateNodeLCP() - not safe under schema ops
+
+Signals:
+
+All but DICT_LOCK are standard v5.0 signals.

-  The server uses ref to store data. ref_length in the above case is the size

-  will maintain. If you are using offsets to mark rows, then current_position

+  SYNOPSIS
+    broadcast_refresh()
+      void                      No parameters.
+
+  DESCRIPTION
+    Due to a bug in a threading library it could happen that a signal
+    did not reach its target. A condition for this was that the same
+    condition variable was used with different mutexes in
+    pthread_cond_wait(). Some time ago we changed LOCK_open to
+    LOCK_global_read_lock in global read lock handling. So COND_refresh
+    was used with LOCK_open and LOCK_global_read_lock.
+
+    We did now also change from COND_refresh to COND_global_read_lock
+    in global read lock handling. But now it is necessary to signal
+    both conditions at the same time.
+
+  NOTE
+    When signalling COND_global_read_lock within the global read lock
+    handling, it is not necessary to also signal COND_refresh.
+
+  RETURN
+    void

+      old_db         [IN] str points to a buffer where to store the old
+                          database, length contains the size of the buffer
+                     [OUT] if old db was not NULL, its name is copied
+                     to the buffer pointed at by str and length is updated
+                     accordingly. Otherwise str[0] is set to '\0' and length
+                     is set to 0. The out parameter should be used only if
+                     the database name has been changed (see dbchangedp).
+
+     dbchangedp      [OUT] is set to TRUE if the current database is changed,
+                     FALSE otherwise. A database is not changed if the old

   SYNOPSIS
     mysql_change_db()
-    thd			Thread handler
-    name		Databasename
-    no_access_check	True don't do access check. In this case name may be ""
+    thd			thread handle
+    name		database name
+    no_access_check	if TRUE, don't do access check. In this
+                        case name may be ""
 
   DESCRIPTION
-    Becasue the database name may have been given directly from the
-    communication packet (in case of 'connect' or 'COM_INIT_DB')
-    we have to do end space removal in this function.
+    Check that the database name corresponds to a valid and
+    existent database, check access rights (unless called with
+    no_access_check), and set the current database. This function
+    is called to change the current database upon user request
+    (COM_CHANGE_DB command) or temporarily, to execute a stored
+    routine.
 
   NOTES
-    Do as little as possible in this function, as it is not called for the
-    replication slave SQL thread (for that thread, setting of thd->db is done
-    in ::exec_event() methods of log_event.cc).
-
-    This function does not send anything, including error messages to the
-    client, if that should be sent to the client, call net_send_error after
-    this function.
+    This function is not the only way to switch the database that
+    is currently employed. When the replication slave thread
+    switches the database before executing a query, it calls
+    thd->set_db directly. However, if the query, in turn, uses
+    a stored routine, the stored routine will use this function,
+    even if it's run on the slave.
+
+    This function allocates the name of the database on the system
+    heap: this is necessary to be able to uniformly change the
+    database from any module of the server. Up to 5.0 different
+    modules were using different memory to store the name of the
+    database, and this led to memory corruption: a stack pointer
+    set by Stored Procedures was used by replication after the
+    stack address was long gone.
+
+    This function does not send anything, including error
+    messages, to the client. If that should be sent to the client,
+    call net_send_error after this function.

+  Check if GROUP BY/DISTINCT can be optimized away because the set is

+  
+  SYNOPSIS
+    list_contains_unique_index ()
+    table                The table to operate on.
+    find_func            function to iterate over the list and search
+                         for a field
+  
+  DESCRIPTION
+    Used in removing the GROUP BY/DISTINCT of the following types of
+    statements:
+      SELECT [DISTINCT] <unique_key_cols>... FROM <single_table_ref>
+        [GROUP BY <unique_key_cols>,...]
+
+    If (a,b,c is distinct)
+      then <any combination of a,b,c>,{whatever} is also distinct
+
+    This function checks if all the key parts of any of the unique keys
+    of the table are referenced by a list : either the select list 
+    through find_field_in_item_list or GROUP BY list through
+    find_field_in_order_list.
+    If the above holds then we can safely remove the GROUP BY/DISTINCT,

+- move "mysqldumpslow" from the client RPM to the server RPM (bug#20216)
+
+- Revert all previous attempts to call "mysql_upgrade" during RPM upgrade,
+  there are some more aspects which need to be solved before this is possible.

+  a newly created temporary directory for the socket to be used
+  in the "mysql_upgrade" operation, overriding any local setting.
